A former Foreign Minister says Winston Peters was right to fire Phil Goff.
Goff made comments at a public event questioning US President Donald Trump's understanding of history.
The remarks have cost him his job as High Commissioner to the UK.
Foreign Affairs was one of a number of portfolios held by Sir Don McKinnon under National.
He told Kerre Woodham it's unacceptable for a diplomat to say such things.
McKinnon says there's a line that ambassadors and High Commissioners should not cross.
